Bought 2000 Buick Century and like many other complaints on the list I have repaired the manifold, water pump, fuel filter at 83,000. I have experienced the whinning and hard shifting the entire time I owned the car. I had intermittent dash light failure which is real dangerous since you can't see the speedometer or anything on the dash. My brakes have failed to brake and I went out into traffic - luckily no accident and there was a median I could steer into! I haven't had a working gas gauge for years. Last night going 70 mph I felt 3 chugs and lost power. Again luckily I was at a freeway exit and could coast off the freeway. So my 3 most expensive bills (and none of the problems have been solved -$1800. For brake calipers, rotors and pads. $1100 for wire set, manifold set, fuel filter and water pump. $350 for headlamp switch and dash light problems. I am putting no more money into this car and up until last night I was looking for a Buick but never again. I didn't put the mileage down when these incidents happened because the symptoms are ongoing!!! it looks like 1000's of complaints have been ignored through the years and the brake issue as well as shutting down going 70 mph are both safety issues which should have been addressed in a recall many years ago!!! I am devastated by the facts I learned researching the computer last night. I am on a fixed income and now without a car too. What reports do I believe when shopping for a new car"????" down below where you date the incident luckily I can say no to all of the questions (but by the grace of god!)
